摘要： An inverter apparatus is provided with first and second current detectors for detecting the current of two arbitrary phases and further with first and second A/D converters, and they are integrated into one unit. It furthermore stores, in a storage device, a compensation value for compensating for an unbalance between gains of the first current detector and the first A/D converter, and gains of the second current detector and the second A/D converter. By multiplying the detected current value of either one of the detected phases by this compensation value, it equalizes the current feedback gains for both phases.

摘要： In the motor driving system, a unit to predict the separation of the wire is built into the power semiconductor module thereby to predict that the time of separation of the wire is approaching before the actual separation of the wire. Thus, the time to replace the power semiconductor module used for power devices such as the motor driving system is clarified to prevent an operation failure of the motor driving system from occurring. The power semiconductor module (1) has a power semiconductor chip (2) mounted thereon, and the power semiconductor chip (2) includes a main circuit wire (4) and a dummy wire (5) connected to the electrode (3) of the power semiconductor. The dummy wire is set to a lower connection strength than the main circuit wire.

摘要： A motor driving apparatus capable of drivingly controlling a plurality of inverter units with a single motor driving command from a motor control unit, and thereby control a large-capacity motor or the like. The motor control unit sends out a single motor driving command (torque command) S. An intermediary unit obtains motor driving commands S×A1 to S×A4 for the inverter units by multiplying the motor driving command S by each of coefficients A1 to A4 set in advance. The inverter units are fed with the motor driving commands S×A1 to S×A4 individually and drive a single motor. Since the motor is driven by the total current supplied by the inverter units, the motor can generate a large torque. The motor control unit only needs to generate a single motor driving command S, and hence only needs to operate a single processing part. Hence, the motor control unit can generate and send out motor driving commands for other motors to drive them.
